According to Chainworld news, Pi Network and Worldcoin each have verified around 18 million users, but they use entirely different methods. Worldcoin verifies users by scanning their irises, while Pi Network verifies users through files and social trust. The token prices of both projects have fallen significantly, and the market is pessimistic about their future. Worldcoin’s users undergo iris scanning using dedicated devices, and the project has over 40 million users across 160 countries, while Pi Network verifies users in more than 200 countries through community verification and document-based KYC. Although the two projects are similar in the number of users they have verified, there are significant differences in market acceptance and token demand.
